Title: Procedure for reestablishing the original cell sequence, in particular in an atm switching system as well as output module for that switch
Inventor: SCHRODI KARL
IPC: H04L12/56
Filed: 1990-12-20
Granted: 1998-12-01
Abstract: State of the art (not public): In order to load an ATM switching network as evenly as possible (even in the short term) and thereby minimise cost, the consecutive cells of one and the same connection are switched through to the exit via as many different paths as possible. 
<??>Technical problem: Reciprocal overtaking of consecutive cells must be avoided or corrected. 
<??>Fundamental principle: Each cell is held at the output until it is ensured that no preceding cell can still be temporarily stored in the switching network. Before the cell is forwarded, a check is carried out to ascertain whether, among the cells leaving the switching network at a later stage, a preceding cell is still present which is to be forwarded before it. 
<??>Implementation: Sequence numbers are assigned to the cells on the input side (either on an individual connection basis or not). On the output side, a buffer memory (1) is provided which is operated at least partially (1, ..., d) in the manner of a shift register and thereby produces a predefined delay. Before the output of a cell, at least the part of the buffer memory which is operated in the manner of a shift register is interrogated to ascertain whether a cell registered at a later stage is to be output earlier. If it is, the two cells are exchanged.

Date Nov. 16, 1989.In a powered member, a device for attaching each end of a flexible tubular chamber to a head of a nipple is formed by a pair of cylindrical bushings interconnected by means of a tenon and mortise joint which are located in the casing and define a central passage having its axis aligned with the axis of the casing. Walls of the passage in a plane drawn in parallel with the longitudinal axis of the casing are in the form of a pair of truncated cones having their larger bases facing towards each other. One generatrix of the conical surface of the passage extends substantially in parallel with generatrix of one conical passage of the head of the nipple and the other generatrix of the passage extends substantially in parallel with the generatrix of the other conical passage of the head of the nipple.

Abstract: The frequency shift keying (FSK) modulation circuit modulates frequency of reference signal using phase  looked  loop  frequency synthesis method  to  generate  stable  FSK  signal.  The  circuit comprises a reference signal generator (10), a phase detector (20) for detecting phase difference of a reference  signal  and  output signal of a frequency divider (60), a low  pass  filter  (30)  for generating DC error signal by filtering error signal of the  phase detector (20), a voltage controlled oscillator (40) for generating frequency controlled by DC error signal,  a  pre-scaler  (50)  for dividing frequency of FSK signal  to  decrease  frequency,  and  a programmable frequency divider (60) for  decreasing  frequency  of output signal of the prescalet (50) down to frequency of reference signal.

Abstract: 집적된 표면 기판에 전기적 경로를 확립하기 위한 저(低)저항 경로가 제공된다. 상기 경로는 p+ 도핑된 외인성 층과 p+ 도핑된 채널정지 영역의 접속에 의해 형성된다. p+ 도핑된 폴리실리콘 접점은 기판 표면상에 배치된다. 한 실시예에 있어서, 금속 실리사이드 층은 상기 폴리실리콘 접점과 접속하고 p+ 도핑된 외인성 층상에 놓인다.

Abstract: 직렬 스캔 경로 통신 아키텍쳐는 다수의 회로(30)를 포함하고, 이 회로들 중 소정의 회로는 메모리(36)를 포함할 수 있다. 메모리 억세스 제어기(38)는 메모리를 갖는 회로들 상에 포함되므로 직렬 데이타가 다중 시프트 동작들을 통해 반복적으로 순환되지 않더라도 메모리들로 기입될 수 있고 이 메모리들로부터 판독될 수 있다.
